Table 1.
The specific values of various parameters of 12 experimental luminaries simulating the tunnel lighting. LP-CCT refers to the CCT simulated by LEDcube. CRI2012 refers to a color difference-based color rendering index; CCT = correlated color temperature; duv refers to the chromaticity difference from the Planckian or daylight locus; CRI = color rendering index; CQS = Color Quality Scale.
